Acts 9:4 - Matthew Poole's English Annotations on the Holy Bible

Saul fell to the earth, struck with the amazing light and terrible voice of Christ; as also with the sense of the presence of God, which he knew was thus reverenced by Daniel, Daniel 8:17, Daniel 10:9. Saul, Saul; the name Saul is the rather mentioned, to mind him and us of his persecuting of Christ in his members, as his name sake had persecuted David, who was a type of Christ; and it is ingeminated, or doubled, not only to rouse and awaken Saul, but to testify his love to him, and commiseration of him. Why persecutest thou me? Christ was in heaven, beyond Saul's rage; but Christ and his church make but one body. Thus Christ says, I was hungry and thirsty, Matthew 25:35. And in all their afflictions he is afflicted, Isaiah 63:9. But me is here emphatically spoken, as if our Saviour had minded him of his great love and mercy to him, in dying and suffering for him; and why then should he persecute him?
